Good stuff but outrageous price policy

The ink is OK (even if it has not kept me from that has been adopted by a mere 8,000 pages of the two print heads) and the paper is really good. Unfortunately, the ink has become more expensive but lately - I bought this set earlier repeatedly for about 30 EURO. Thus the cost of a complete set of color with black (~ 20) about 50. Today, the set costs with 4 colors and without paper (it is around 10) over 70. Well I'll look at times like Epson WorkForce series in the Prices developed.
